I am having a very difficult time finding a supplier of cap screws in the US willing to comply with the EN 10204 Type 2.2 documentation. Does anyone know of one?
You may need to go to Europe to find them. We supply flange bolting to the oil & gas industry with 3.1b certification and buy mostly from Tripplefast in the UK and OME out of Italy. I also have some M8x45 socket head cap screws in F55 on my desk if you are interested ;-) (client decided that they needed titanium instead).
Oh - expect to spend $$ though. Metal with paper behind it is not cheap.
